Manage files in Yahoo Groups

Group owners and moderators can restrict access to some features. If the Files or Upload options aren’t available, request access from the owner or moderators. There’s a limit of 5MB per file, attachment, or photo and a total storage limit of 100MB. Everything posted on the Files, Attachments, or Photos pages counts towards that. Messages containing certain attachment file types won't be delivered: .exe, .vps, .pif, .scr, .bat.
